Used in biodegradable plastics for packaging, disposable tableware, and shopping bags due to its eco-friendly nature. Common in 3D printing filaments because it melts at low temperatures and flows well. Applied in medical devices such as sutures, stents, and drug delivery systems, as it safely breaks down in the body over time. Also used in textiles for making biodegradable fibers in clothing and agricultural mulch films that degrade naturally in soil.
